ReactiveUI.Primitives.Reactive.Concurrency namespace¶

Part of the ReactiveUI.Primitives.Reactive package.

Type	Kind	Summary
HandlerSequencer	class	System.Reactive-flavoured Android scheduler that coalesces scheduled work onto the thread backing a [Handler](# (typically the main/UI looper). Immediate work is batched through a single cached `IRunnable` drain, so the per-post path allocates nothing; delayed work uses the native `PostDelayed`.
NSRunloopSequencer	class	System.Reactive-flavoured Apple scheduler that coalesces scheduled work onto the main `DispatchQueue` (the UI thread on iOS, tvOS, Mac Catalyst, and macOS). Immediate work is batched through a single cached `DispatchBlock` drain, so the per-post path allocates nothing; delayed work uses `DispatchAfter`.
ScheduledItem	class	Creates materialized [ScheduledItem](# work items from a sequencer, state, and action.
WasmScheduler	class	Task-pool replacement for single-threaded event-loop runtimes such as browser WebAssembly: it never starts threads, never blocks, and does not support long-running scheduling. Immediate work is batched one drain per event-loop turn through a zero-due timer (a `setTimeout(0)` macrotask on WebAssembly, so the browser can render between batches); delayed and periodic work use one-shot/periodic timers, which the WebAssembly runtime backs with the JS event loop. Successor to the retired `Reactive.Wasm` package's scheduler, whose runtime reflection no longer exists on modern .NET.
